I have a 2005 Maxum; 350 MPI Bravo III outdrive -- acting as follows:
- About 3000 rpm a loud growl occurs that vibrates the boat. RPM?s seem to rev and speed declines.
- It occurs on turns and going straight at or above 3000 rpms.
- I?ve had a mechanic pull the outdrive and have confirmed u-joints and gimble bearing is good.
- I?ve taken it to a second mechanic and he has confirmed no outdrive issues he thinks it?s most likely the Clone Clutch
- WOT is 4300 rpm ? I do have an altitude issue I need to deal with by upgrading gear ratio from 2.0:1 to 2.2:1 ? this is separate issue.

I wish I could take ya?ll out on the boat so you could hear but I can?t.

I wanted to run this post by y?all to see if anyone has had a clone clutch issue and what were the symptons.
